OLYMPICS

Britain's former drugs cheats can compete at London 2012 after a court overturned the British Olympic Association's policy of lifetime bans.

The BOA has lost its battle with the World Anti-Doping Agency (Wada) at the Court of Arbitration for Sport (Cas).

It means the likes of sprinter Dwain Chambers and cyclist David Millar can try to qualify for Team GB.

The Cas ruling was expected after the reigning Olympic 400m champion LaShawn Merritt last year won his appeal against an IOC doping law which prohibited any athlete given a ban longer than six months from competing at the next Games.
